Here's my thoughts on it.

Finally got a few flight in... cheap ESC cause me to the strip the main gear so was down a few days. But everything work great now.

So here's my thoughts.

- SK720 is a major improvement from SK360, smarter, smoother.
- The basic 3D set up work really good, so for most Mild 3D pilot, you're set.
- The tail feel just like my Futaba GY611 (however I am still trying to tune out the piroquette stopping). But it very good so far.

3D wise, again I am still tuning it.

- Axial flip
- Axial roll
- Tic toc are less violent than the SK360
- Piro flip are reasonable with the Basic set up

My 2cents against other flybarless I have tried?

Better than the Align 3G for sure (because of the tune-ability) it just feel more smoother and does not have elevator bounce upon first take off.

Also, I felt this was Easier to understand than the Vbar, the tail feel much more tuned vs the Vbar for the first flight. I did not have to do anything. The Vbar it took me 3-4 flight to get the tail to work right. Overall, if I have to choose, I would chose the SK720 over the Vbar.

Again, not trying to start a war, just my opinion.

Video coming soon... sorry. It been windy as hell here for the pass week.

2150rpm for headspeed, 5 min of average 3D, using about 1700mah out of 3300mah. Will bang the stick once I get a Jive in there, Castle Gov never work for me.

Drive way video.

Yes, it does... a big improvement over the SK360. In the video I just couldn't get my finger to stop shaking, since there's a lot of liabilty flying in front of your drive way... and had to keep an eyes for coming cars.

But it does piro fast and stay in one spot.

If i got $, I will run my T-rex on 10s lithium.

_ Cut paste below. I posted the flight log on rc grewps in the 720 thread.

Well, Just had my first crash w/ the 720, and it appears it was a failure of the unit? I've flown it about 20 times. Plugged in the lipo and got the usual up down of the swash, then checked for a solid green light and proper control movement. Sat the heli down, and did like I always do, switched into idle up one. Picked it up into a nice stable hover, it banked to the right and wouldn't correct. All it did was take out the blades, but I am worried- the flight log is just wild, take a look. I only took off the heli once, but it shows it taking off twice, first time w/ the stick at idle?? Afterwards the unit appears to function normally, but heck it did before also

Well the unit starts logging when power is on. First take off was when you carried the heli to take off point.

Then it looks like you gave some right input on take off then all hell broke loose?

Keep, if what you're saying is correct, then why don't the other 19 flight logs I have show a different flight and landing each time I carry it to the take off point? Not that it takes me 38 seconds to do so either, more like 5-10 seconds. Not a bad servo, that was the first thing I checked. I have now gone over it with a fine tooth comb and nothing is wrong with it. Believe me, I have 2 more of these ordered, no one wants to find another explanation more than me right now. It flew PERFECT, till this happened. The flight ( if you can call it that ) started at 39 sec. into the log, which is far from displaying it perfectly. It lifted to 3 feet, then banked right until it went in. As soon as it started banking right, I began applying left with no result.

Brownout would show as voltage loss on the playback and blinking satellites. I had neither. Static hit maybe, but unlikly with a shaft drive tail.

I reloaded the setup and re-bound, I'll try it again tomorrow.

Then I really dont know man.. I know on some of my logs it records my walking with the heli but does not show motor running??!!

Are you sure fail safe didnt kick in? Did you have control over the unit and was the unit blinking red after the crash?

Just trying to give some more ideas to help you trouble shoot. Try sending the log to skookum. They can read alot more than the player shows, like system erros and those type of things!

I will post your log on the beta forum also!

Thanks Ken. The unit was still solid green after the crash, it didn't go into failsafe. I'll report again after I fly again.

Flybarless puts a lot of strain on servos. That’s why I only use Futaba BLS servos and Futaba FASST receivers for my flybarless helicopters. I have never had a problem after I switched from Spektrum to Futaba.
